HPWC

So the electrician came to my house and installed a 50amp breaker and the unit, he does not want to mess with the setting at all so when he left, he claimed that he hooked everything up properly, but I kept on getting those 3 blinking lights, would any of you please tell me what might have gone...

This seems to be a recurring topic, so I thought I would share. Familiar with HPWC installs as he has done multiple. Did a great job, very clean install, on time, on budget. When others insisted that I upgrade my panel without gathering any supporting data, he walked me carefully through my...

Trying to save some time and have materials ready for electrician. What materials are needed to install HPWC if your garage breaker has plenty of room and is newish (2007 Siemens) 100AMP breaker 3awg copper wire in whatever length necessary Electrician should have rest? TIA

I know the OEM new goes for $500-550 depending on cable length. Anyone have one in like new condition to sell? Thanks

Hi forum- I'm in the process of getting an HPWC installed, and I would like to feed it with 100A (as I have a 72A charger in my X). I also have a 20kW Generac whole-house generator with an automatic transfer switch. My electrician is looking at some options for how to do the install. I've...

All I need is the end where the adapters would plug in. If you have an extra UMC, I'm interested - even if it's not working, that's OK.

hi all! My model s comes Tuesday, before my garage can be built, so we are installing the hpwc on the outside of the house in the meantime. My question is: We have a 200 amp breaker box, the copper wiring to the garage is on a 100 amp breaker. Will this be ok to plug directly into the HPWC? If...

While I wait for my Model 3 I wanted to get my garage wired up for EV charging. My question is focused on whether or not its worth it to pre-wire for 80 amps? My initial plan is to charge my M3 during the night at 40a via a NEMA 14-50 outlet; however as I learn more about how I use my Telsa and...

Hello, My S60D arrives in about a week, and I have already had my electrician install a 14-50 in the garage, ready to go. I did not get the "dual chargers" option because for now I think the single charger will be enough, and my whole house only has 100A service, so likely I could not...

Got a email from Telstra last week re my Model X order (to be delivered late Dec in Sydney). They have asked me to specify the 2.7m or 7.7m charging cable for the HPWC. I can probably live with the shorter one, but then again the longer might occasionally come in handy. My questions is how much...

today, when I attach the roadster to the HPWC connector, it's not registering the connection. The green light on the wall unit is on. The VDS says: "Preparing to Charge Connect power cable" When i slide up the lock, nothing happens. No blue light. Nothing. Just the usual white light from the...

I have the 20" HPWC cable. Any way you can extend with any sort of custom or non-custom coupler? I'd love to be able to plug in while parked outside my garage as well, and it seems pretty excessive to install a HPWC or outlet OUTSIDE my garage as well. Danke!

I'm planning my electrical work to my detached garage and my electrician said I only have room to run max 60 amps to a subpanel in the garage, not 100. Ideally I would like the convenience of the HPWC plus a 14-50 outlet for backup and compatibility with other cars, but I wouldn't use the two...

The HPWC was purchased last April at the time of the car and have had zero problems since. I just noticed when I plugged it in a few minutes ago, I didn't hear the contacts close and noticed on the screen it says, "No Wall Power - Check power source. Charging stopped". I pressed the reset...

has any one successfully received their rebate after purchasing the HPWC from tesla.com? I understood that in order to qualify, it had to be purchased from a Canadian source but the receipt from Tesla.com is US based.

I am going to install a HPWC at my business. I want to restrict use only to people who come in for a code, or something like that. Can anyone think of a way to install a keypad, or something similar, that only allows use of the HPWC when a code is entered? Thanks in advance.

I'm still trying to decide if I should buy a HPWC or just install a NEMA 14-50, I stopped at the local hardware store and picked up on 14-50 outlet, it is different than the others i've seen and it doesn't say NEMA anywhere on it. I attached pictures and was wondering will this work if I got...

I am in the process of getting everything ready for my upcoming model x delivery. I just installed my HPWC. The unit is installed off of a newly installed 100 amp sub panel in my garage. I am currently only using a 60 amp breaker to the HPWC. However I have run into an issue. The HPWC will not...

We have an extra UMC but my wife prefers the aesthetic of the HPWC. Is anybody interested in trading?

HPWC for Tesla Model S or X. Old or new version.

Now my Roadster has gone ....... Tesla — Roadster High Power Wall Connector Just like this one - never used or even taken out of the box ! $1000 - ono plus postage.

I called an electrician listed on Tesla's Web site to install a HPWC in my garage. It's a simple install - the HPWC will be mounted right next to my electrical panel. It'll be installed on a 60amp circuit for 48amp output. His quote was $600 (includes all materials, permits, etc. etc.). Is this...

West coast even better!

Please contact me if you are selling a HPWC with a 24' cord. Please note that Tesla is selling these new for $550 on Tesla.com. Thanks!!!

If this poll already exists please forgive me :confused: I totally understand why Tesla would have been hesitant to add HPWCs initially... unless I'm mistaken the Superchargers use 480v and HPWCs used 240v so you would have needed an additional transformer to power the HPWCs. Now that HPWCs...

Hey guys, I want to install a HPWC and a 14-50 for dual use so I wanted to ask what I would need installed. Ideally, I would want to use the HPWC to power either a single or dual charger and I would also like a 14-50 outlet that is hot as well. What would I need to have installed to power...

Hello, we have recently traded in our well loved 2013 (delivered December 24/2013) Tesla Model S. At this time we aren't replacing it so.... We have 2 Generation 1 highpowered wall chargers. We paid $1287.00 each. One has been used under 5 times. It was installed at a cottage. Second charged a...

Reading about the congestion at some superchargers in California on high travel days got me thinking... Obviously installing HPWC's is far cheaper then supercharger cabinets, but at the same time, the charging is much (much) slower. Tesla has standardized on the single charger that for most is...

Question for people who have installed the new style of Wall Connector (AKA HPWC) -- one that has the built-in wire hanger. How high did you mount it off the ground or floor? I will be installing mine outdoors, in an area subject to snow, so it must be installed high enough to avoid having the...

This may have just been a glitch, or it may be the first instance of a problem that might get worse. I drove the car for the first time in 2 days on Saturday. When I got in the 90% charge level only said 264 and it's usually 268 or 269. I was thinking the battery might need conditioning, but...

As I am (seriously) shopping for a CPO Tesla, does anyone have an electrician they would recommend for install of the HPWC (100 amp....dual charger capable) and/or Nema 14-50? I'm in the Grapevine area (e.g. near the DFW airport)? I'm not looking to get reamed on the install cost of course...

when my HPWC was first installed I'm sure I got aprox. 50 km/hr on the charger. Now 3 months later I only seem to get 33 km/hr. I've read that if it is 3 phase charging there should be a small 3 in a circle on the display. That is not there, and I can't remember if it was ever there. Does...

My automatic overnight charging level set for 48 A. I noticed last night's charging cycle was reduced to 16 A for the whole period. What would be the cause of such a significant reduction in charge rate?

Ive owned my Model X for two days. Used my HPWC three times. I just got home and instead of shining green it's shining red (see pic). Is this bad? What does it mean?

Is 6/3 cable fine for the HPWC with a 60a breaker?

Model S arriving shortly, but 2nd vehicle in garage in next year or two may or may not be a Tesla. We want to future-proof things by getting a more generic J1772 (80 amp) vs the HPWC. I'm guessing there are many options for the high-amp J1772 EVSE; is there a go-to piece of equipment people are...

What size wire has everyone been using for their HPWC install? The manual says #2 copper but that seems overkill. In the top entry extended back they shipped with the charger it only had #4 copper. I was thinking of getting #3 copper just to be safe.

Anyone do this? I have the outlet at my office and I am getting tired of taking the EVSE in and out of the trunk. I know the HPWC will be restricted to 40 Amp. I was wondering how easy/difficult it is to do with the line already there. It would also be in a place where it is outdoors under a...

I see on Tesla's website that the HPWC unit has been redesigned and is even cheaper now. Page 5 of the manual states at the top, "The maximum power rating for the Wall Connector is 20 kW or 80A at 250V AC single-phase power. Your vehicle can charge from 200V to 277V single-phase power." It just...

The Ministry is providing up to $1,000 in rebates to install a charger in your home. This is great for so many reasons, and the process of filling out the forms seems simple enough. Kudos Canada. The catch is you actually have to have already purchased an EV to apply for the Charging Incentive...

We had our house pre-wired for the car charger and they installed 40A (it's the highest they would go, for some odd reason). The wiring is already behind the wall, so it's nice and clean. Though the garage walls aren't finished now, we do plan to finish the garage sometime in the next year or...

I'm pre-ordering a Model 3 and considering installing a charger now to take advantage of the federal EV infrastructure tax credit. I was wondering though is it possible to have a NEMA 14-50 outlet installed then upgrade that outlet at a later time to a HPWC?

I've got an opportunity to install an Archimedean screw micro hydro scheme for power generation on a river running alongside my business and was planning on using the energy generated to power my MX and the 3s (when they arrive). I've been told that the turbine will generate 5kW peak power...

Installation of my HPWC is complete. I'm not really charging at a super fast rate. I got the HPWC because I didn't want to take my cord out of my car every single day to charge. So this way I can pull up and plug in. Its getting about 20 miles an hour right now, which my car is parked for 9...

Hey guys, Just wanted to ask a question, I have a HPWC connected on a single phase 32amp circuit. My model S only has a single charger. What charging rates should I be getting? I swear I used to get 50km/hr but the last few times I'm getting a charging rate at 33km/hr. Does this seem right...

I recently had two HPWC professionally installed on a single 100A circuit (see photo) in my garage. The electrician set the master unit to a maximum output current of 40A (rotary switch position 8). In this setting, it was only able to charge a single updated MS at 40A rather than 48A. Would...

Folks.. Brand new model S... I had ordered the 72 amp upgrade. Also got HPWC installed at home. Plugged it in for the first time and it is getting 48amp from HPWC. Is this an HPWC installation issue or some setting I need to turn on? Pic attached

Hi all, Our 90D was delivered in late March just as the new HPWC was announced. We were the first install of the new HPWC for our local electric company (who installs many Tesla setups here in the Bay Area). They installed a new 200A panel and ran 40A to the front of the house where the HPWC...

Has anyone else compared the new HPWC manual to the old manual? The new one is comparatively unpolished and has a number of minor errors (I found at least 3). The one I'm struggling with is: - Page 18, Step 5: "Connect the wiring to .. the ground wires going to the locations shown in the...

I have often wondered about the holes that will remain in the Supercharger network even when it is complete/established. The USA is so large geographically and has many rural areas that need/will need coverage, but a full-on Supercharger would be overkill or too costly for the near-term. I...
